1 Claim.

7 This invention is a jack-d-lantern and electric bulb holding unit.

It is an object of this invention to provide a safety jack-o'-lantern and illumination device whereby to reduce the hazard of fire such as is incident to the use of open-flame candles in paper boxes.

Another object of the invention is to provide. a simple, practical, substantial and very low cost means for holding and attaching an electric battery to a given supporting part.

A further object is to provide a battery holder with but a single structural body and which is provided with means to grip the opposite sides of an applied battery and incorporates abasal limb having impaling means to attach to any convenient, impalable supporting element.

The invention consists of certain improvements in this art as set forth in the ensuing disclosure and having, with the above, additional objects and advantages as hereinafter developed, and whose construction, combination and details of means and the manner of operation, and one use of the device, will be made manifest in the description of the herewith illustrative apparatus; it being understood that modifications, variations and adaptations may be resorted to within the scope, spirit and principle of the invention as it is more directly claimed hereinbelow.

Figure l is a perspective of a jack-o-lantern, the bottom of which is broken away to show the installed bulb holder;

Figure 2 is a perspective of the holder ready for application of a battery.

Figure 3 is a side elevation of the holder with an applied battery and a bulb mounted on the holder and in open circuit position.

A feature of this invention is that it is entirely complete in itself for all of the desired functions to be accomplished and needs no extraneous fixation means either as to the mounting of the holder on a desired support or any special type of battery structure to effect a coupling of the battery and the holder as will now be explained.

From a fiat pieceof sheet metal of suitable gage there is stamped or punched out an elongate body or backbone 2 of a length and width according to the size of battery B which is to be held and affixed. At the lower or bottom end of the body 2 a portion is bent forwardly at a right angle to form a footing 3 to receive the bottom of the battery. This footing is provided with an afilxing means here in the form of a pair of pointed prongs 4 perpendicular to. the bottom face of the footing and at its opposite sides.

which is perforated at 1. to screwably receive the 1 threaded bulb m'ountingM. The bracket is designed to normally stay at such a position over the upper terminal of the battery B that when the bulb is screwed in its center terminal from the filament can be brought firmly against the 15 corresponding terminal of the battery so that a good circuit will be completed through the A grounded bottom of the battery on the footing 3 and thence through the body to the mounting M of the bulb. If it is desired to open the circuit go it is only necessary to screw the bulb out a short distance from the battery, center terminal. It will be seen that all forms of special means to open and close the circuit are eliminated by the device of this invention.

It is understood that the prongs 4 may be used for aifixing the holder to any appropriate support and it is not limited to the application only of a jack-o-lantem.

Other than the simple resilient side arms 5-5, the one-piece holder here disclosed is entirely free from movably operative parts. The circuit is controlled entirely by adjustment of the lamp bulb in the bracket 6, and no special switching means are involved to add to the cost of the holder.

In its normal, idle position the bracket is effective to hold a partly screwed in bulb in circuit closing contact on the-battery and the circuit is broken by back-screwing the bulb without functional change'of position of the bracket.

The side arms 5--5 are sufllciently resilient to spread fr'om their normally, slightly converged position, Fig. 2, and efiectively grip the interposed battery. Small dry batteries are the backbone, flat, resilient arms bent and extending from the same side of the backbone as the said lugs and in spaced converging relation to receive the given battery and hold it in a. position between the lugs and in alinement therewith, and the bottom lug having spaced prongs downwardly extending from its sides below the said arms whereby to am the holding device to an appropriate support the top lug being periorated to threadediy receive a bulb base.
